In n8n versions before 1.123.76, 2.37.7, and 2.38.2, the source control push endpoint derived the set of files to push from the file paths and status supplied in the client request payload instead of from the server-side status computed for the requesting user. An authenticated project-scoped user (e.g., a project admin) could therefore reference files belonging to projects they have no access to and push a deletion of those projects' workflows and credentials, resulting in cross-project data destruction. Exploitation requires the Source Control (Environments) enterprise feature to be licensed, enabled, and connected to a remote repository. The issue is fixed in 1.123.76, 2.37.7, and 2.38.2.","score":5.9,"severity":"medium","published":"2026-09-16T21:46:54.429Z","modified":"2026-10-29T21:17:09.865Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"n8n-io","name":"n8n","platforms":[],"versions":[{"version":"0","status":"affected","lessThan":"1.123.76","versionType":"semver"},{"version":"1.123.76","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected","packageURL":"pkg:npm/n8n","packageIdentity":{"ecosystem":"npm","name":"n8n"},"cpes":[],"source":"VulnCheck","url":"https://www.cve.org/CVERecord?id=CVE-2026-92588"},{"vendor":"n8n-io","name":"n8n","platforms":[],"versions":[{"version":"2.38.0","status":"affected","lessThan":"2.38.2","versionType":"semver"},{"version":"2.38.2","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected","packageURL":"pkg:npm/n8n","packageIdentity":{"ecosystem":"npm","name":"n8n"},"cpes":[],"source":"VulnCheck","url":"https://www.cve.org/CVERecord?id=CVE-2026-92588"},{"vendor":"n8n-io","name":"n8n","platforms":[],"versions":[{"version":"2.0.0-rc.0","status":"affected","lessThan":"2.37.7","versionType":"semver"},{"version":"2.37.7","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected","packageURL":"pkg:npm/n8n","packageIdentity":{"ecosystem":"npm","name":"n8n"},"cpes":[],"source":"VulnCheck","url":"https://www.cve.org/CVERecord?id=CVE-2026-92588"}],"remediation":[],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-hvrx-jc5j-pg3w","https://www.vulncheck.com/advisories/n8n-before-1.123.76-improper-authorization-via-source-control-push"],"sources":[{"name":"CVE","id":"CVE-2026-92588","modified":"2026-10-29T21:17:09.865Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-92588"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":5.9},{"source":"VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N","score":4.4}],"sourceAffected":[],"observedAt":"2026-10-29T21:38:12.178Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T11:25:31.829Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-29T21:20:35.896Z","attemptedAt":"2026-10-29T21:20:35.896Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-29T21:20:36.305Z","attemptedAt":"2026-10-29T21:20:36.305Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-29T21:20:36.350Z","attemptedAt":"2026-10-29T21:20:36.350Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-29T21:20:35.707Z","attemptedAt":"2026-10-29T21:20:35.707Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-92588","url":"https://www.first.org/epss/","probability":0.00322,"percentile":0.25133,"date":"2026-10-29","checkedAt":"2026-10-29T21:20:35.707Z"},{"source":"NVD","id":"CVE-2026-92588","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92588","modified":"2026-10-29T21:17:36.150","score":5.9,"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","checkedAt":"2026-10-29T21:20:35.896Z"},{"source":"NVD","id":"CVE-2026-92588","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92588","modified":"2026-10-29T21:17:36.150","score":4.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N","checkedAt":"2026-10-29T21:20:35.896Z"},{"source":"GitHub Advisory Database","id":"GHSA-cr47-hhfm-v884","url":"https://github.com/advisories/GHSA-cr47-hhfm-v884","modified":"2026-09-17T00:31:27Z","score":4.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N","checkedAt":"2026-10-29T21:20:36.305Z"},{"source":"ENISA EUVD","id":"EUVD-2026-81288","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-81288","modified":"Oct 29, 2026, 8:20:29 PM","score":5.9,"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","checkedAt":"2026-10-29T21:20:36.350Z"}],"aiSummary":{"text":"n8n versions before 1.123.76, 2.37.7, and 2.38.2 have an improper authorization vulnerability, allowing an authenticated project-scoped user to push deletions of files they don't have access to.
